4th stage. Larvae, black granulated with white; long white hairs; horns,
brown-orange with white tips; on each segment two brown spots. Spiracles
well marked with outer circle, brown, then black; white and black dot in
the center. Anal segment with brown ribs, the intervals black with white
dots; head shining, black with two brown bands on the face, forming a
triangle. Other larvae in fourth stage, velvety black, with coral-red
spines; others with black spines.

5th stage. Larvae, entirely black, with showy eye-like spiracles,
polished black head; other larvae having the head brown and black. Larvae
covered with long white hair; spines black or red. No difference noticed
between the fifth and sixth stages.

One larva on fourth stage was different from all others, and was
described at the British Museum by Mr. W. F. Kirby as follows: "Larva
reddish-brown, sparingly clothed with long slender white hairs, with
four reddish stripes on the face, two rows of red spots on the back,
spiracles surrounded with yellow, black and red rings; legs red, prolegs
black, spotted with red. On segments three and four are four long
coral-red fleshy-branched spines, two on each segment, below which, on
each side, are two rudimentary ones just behind the head; in front of
segment two are four similar rudimentary orange spines or tubercles;
last segment black, strongly granulated and edges triangularly above and
at the sides, with coral-red; several short rudimentary fleshy spines
rising from the red portion; the last segment but one is reddish above,
with a short red spine in the middle, and the one before it has a long
coral-red spine in the middle similar to those of segments three and
four, but shorter"
